Collins, 67, is involved in a contentious divorce with Grant. But she told E! News she had nothing to do with the release of the recording.

"I woke up today to learn that an extremely private recording I handed over to authorities in 2012 per their request in connection with a criminal investigation was recently disseminated to the press," she said. "I had no involvement whatsoever with the release of the tape to the media."

A can of worms

The revelation opened up a whole can of worms for the actor, best known for playing a pastor on the TV show, "7th Heaven," which ran for 11 years.

The gist of it is this: A relative of Collins' first wife went to police in November 2012 and told them she was sexually assaulted by Collins when she was 14 years old while inside his New York apartment, a senior law enforcement official told CNN on Tuesday evening.

Due to the statue of limitations, he can't face charges in the case. There are specific laws with child sexual abuse cases in New York that allow for an extension of the statute of limitations, but even with that, this particular case against Collins can't be prosecuted, the official added.

Now, the investigation continues to see if there might be any other women with similar allegations, the source said.

(In New York, a person has five years from their 18th birthday to make an accusation of sexual abuse to authorities.)

Los Angeles police said they received information two years ago regarding allegations of criminal behavior.

The case is no longer active, LAPD spokesman Andrew Neiman said.

"No crime report was ever made and there was no verified victim," he said.

The fallout

Following the revelation, Collins was fired from his job on the movie "Ted 2."

He also resigned Tuesday from his spot on the national board of the Screen Actor's Guild, a source at the organization with knowledge of the situation told CNN.

And UPtv, a family-friendly network, said it was pulling reruns of "7th Heaven" from its lineup because it was "deeply concerned for the families that are potentially affected by these disturbing allegations."

The accusations

The accusations are explosive.

According to divorce documents filed in Los Angeles County Superior Court, Grant says she learned Collins had "been engaging in a long-term pattern of sexually molesting children." She said Collins admitted to her that he molested three underage girls more than a decade prior, the court document says.

Neither Collins' attorney nor his agent immediately returned any of CNN's numerous calls. Grant's representatives also didn't respond to requests for comment.

Grant said in the court documents that she was unaware of Collins' behavior until he told her in January 2012. They separated the next month, after almost 27 years of marriage.

In Collins' legal response to the divorce filing, his lawyer doesn't specifically address the claims made by Grant, though he does write that it "is really an attempt to extort concessions in settlement."
